A standard assumption underlying traditional accounts of belief change is the principle of minimal change, that an agent’s belief state should be modified minimally to incorporate new information. In this paper we introduce a novel account of belief change in which the agent’s belief state is modified minimally to incorporate exactly the new information. Thus a revision by p∨q will result in a ...

Human learning may depend upon domain specialized mechanisms. A plausible example is rapid, early learning about the thoughts and feelings of other people. A major achievement in this domain, at about age four in the typically developing child, is the ability to solve problems in which the child attributes false beliefs to other people and predicts their actions. The main focus of theorizing ha...

Motivated by its success in decoding turbo codes, we provide an analysis of the belief propagation algorithm on the turbo decoding graph with Gaussian densities. In this context, we are able to show that, under certain conditions, the algorithm converges and that – somewhat surprisingly – though the density generated by belief propagation may differ significantly from the desired posterior dens...

In traditional formal approaches to knowledge representation, agents are assumed to believe all the logical consequences of their knowledge bases. As a result, reasoning in the rst-order case becomes undecidable. Since real agents are constrained by resource limitations , it seems appropriate to look for weaker forms of reasoning with better computational properties. One way to approach the pro...

121 Generalized Versions of Turbo Decoding in the Framework of Bayesian Networks and Pearl's Belief Propagation Algorithm Peyman Meshkat and John D. Villasenor Electrical Engineering Department University of California, Los Angeles Abstract| We use the framework of Bayesian networks to introduce generalizations of the traditional turbo decoding algorithm. We show that traditional turbo decoding...

This paper reports on health beliefs and their influence on treatment decisions and behaviour among the Esan people of mid-west Nigeria. The sources for the study are my own experience of growing up in Esan society, anthropological field work, and focus groups. The research revealed a transitional society where both traditional and modern medicine are employed and where the choice between the...
